II对整个硬件系统进行综合，布局布线，仿真等，用集成化开发环境IDE来进行应用软件的开发和调试 |
[2004-6-24 10:55:08] |
| [问：greg828] |
Nios
II軟核處理器與單片機有什麽不同，是否可以實現多串口通訊？ |
| [答：Sam] |
基本上NIOS II 為一個soft core IP,可以放進Altera
FPGA,因為擴充性靈活,只要FPGA的容量過大,即可利用SOPC
Builder去定做自己要的處理器,當然也可定做Muti-UART的處理器 |
[2004-6-24 10:56:35] |
| [问：rean] |
請問是否能將自己設計的IP整合至SOPC
Builder的圖形介面中，以方便未來整合時像其他SOPC Builder原有的IP整合一樣方便？ |

可利用Interface to user logic 整合NIOS and your IP. |
[2004-6-24 10:56:54] |
| [问：tlyangbenq] |
What is different of Nios and
NiosII? |
| [答：Bill] |
Nios
II是在第一代Nios基础上升级而来的第二代嵌入式软核处理器。比第一代的性能更高，占用的逻辑资源更少。还提供了更多的特性。其具体参数和性能请参考刚才演讲中的内容。 |
[2004-6-24 10:57:32] |
| [问：sdawang] |
DMIPS的中文解释？ |
| [答：Bill] |
MIPS的意思是每秒百万条指令，如果一个CPU在一秒钟可以执行50个百万条指令，那么他的MIPS就是50，而DMIPS则是在CPU上运行一个测试程序，由测试程序测试得出的一个相对的数值。 |
[2004-6-24 10:59:34] |
| [问：rean] |
Can IS Simulator simulate user-defined
instruction? (co-simulation with appended hardware) |

| [答：Elliott] |
Nios II have 32 bit data path and 32 bit instructions and flat
register file and 32 prioritized interrupts and branch prediction, and can
into an OS.if you use stratix II ,nios II can run 220
DMIPS. |
[2004-6-24 11:01:51] |
| [问：58868] |
is there data protection? |
| [答：Andy] |
If you mean that the data protection when configuration, there are two
solution can let you choose, one is adding one CPLD(MAX3000) with your
FPGA, and then add security code to CPLD and FPGA, then you will get the
security function, please contact your FAE for the detail, another one is
choose STRATIX II, it has security function. |
[2004-6-24 11:02:13] |
| [问：gaozg] |
请问altLVDS megafunction是否可以直接挂接在avalon
bus？ |
| [答：Bill] |
您还是应该在中间设计一个接口模块，从而使altLVDS Megafunction的时序与avalon
bus相配合，而且你也需要设置控制寄存器和状态寄存器来操作这个外设 |
[2004-6-24 11:02:33] |
| [问：xuanwei] |

Actually,you can implement any DSP function in the FPGA, then use it
as a peripheral. |
[2004-6-24 11:08:09] |
| [问：hugoshiuaa] |
我以前使用過APEX20K系列的晶片，它的使用與NIOS有多大差別？ |
| [答：Sam] |
NIOS 為soft core IP,它可以利用Quartus II and SOPC Builder去產生FPGA
燒錄檔,但建議您還是使用Cyclone,Stratix and Stratix II FPGA. |

如果您指的是ALTERA的demoboard,那麼您所需要的A/D,D/A或是PCI介面(depends on your
demoboard)都已經建在板子上. |
[2004-6-24 11:14:12] |
| [问：greg828] |
NIOS II軟處理器中的FPGA利用率有多高? |
| [答：Elliott] |
the niosII has 3 versions as below:1. economy: ~700 LEs2.
standard: ~1000 LEs3. full function: ~1400 LEsthe usage rate
is depend on which device you choosed. by example:you choose 1S10
device ==> 10000 LEsand choose standard version ==> 1000
LEsthe usage is 1000/10000 = 10% |
[2004-6-24 11:18:11] |
| [问：hans07] |
Dear Sir : How do I construct
a special module hardware and driver in NIOS II (eg. LCD
controller)? |
| [答：Bill] |
SOPC Builder can incorporate a block of user-logic by instantiating it
directly within the system module. SOPC Builder will create bus-logic and
connect it to all designated master or slave interfaces on the
user-designed block,please refer SOPC Builder datasheet. |
[2004-6-24 11:21:11] |
| [问：chenfx] |
请问：是否能提供几种不同型势的开发例程。谢谢！ |

as a general purpose processor. you can replace 80XX, arm7,....the
advantage is you can have most flexities. |
[2004-6-24 11:21:42] |
| [问：sllin11] |
You said the hardcore and softcore, what’s
the main different? thanks |
| [答：Sam] |
NIOS 為softcore IP,彈性較大,可任意擴充,Hardcore則為一個硬體,已經直接放在Altera
FPGA裡 |
[2004-6-24 11:21:45] |
| [问：hugoshiuaa] |
使用Nios II 處理器對開發硬體有什麽好處？ |

使用SOPC Builder設計工具和Nios
II軟核處理器可以在可編程晶片上創建一嵌入式系統，其系統的整體性能（如即時性）如何確定，需考慮哪些方面？ |
| [答：Brian] |
We have run Dhrystone Benchmarks over NiosII and the fast variant can
get to 1.19DMIPS/MHz. As for overall system performance, one advantage of
SoPC is that you can boost performance easily using custom instruction
& logic. |
[2004-6-24 11:23:12] |
| [问：tlyangbenq] |
與單片機或者PLC相比，嵌入式系統在工業現場控制（如自動化流水線）方面有何優勢？ |
| [答：Sam] |
因為NIOS 為softcore IP
,需配合FPGA來使用,所以FOGA除了NIOS外還可將周邊數位電路一起放進FPGA裡,當然PCB電路設計和被料就簡單多了 |
[2004-6-24 11:26:02] |
| [问：greg828] |
Nios II與ARM處理器相比，優勢是什麽？ |
| [答：Bill] |
Nios
II最大的优点是它的灵活性，就是说CPU的性能，外设，甚至指令都是可以根据实际的需求自己来定制，这样你的产品就不会在不需要的地方浪费不必要的投资。当然还有很多其他优势，诸如快速的上市时间，高性能，低成本，可以移植到最新工艺的FPGA芯片上等等 |

| [问：ecnan
jing_EBY7E] |
请问,可否在同一个FPGA上同时嵌入硬核和软核?如可以,它们的时序配合有何讲究?谢谢! |
| [答：Brian] |
You can put soft-core on any FPGA we provided but for hard-core,
Altera only provide Excalibur-ARM device. But you can certainly put Nios
on FPGA fabric of this devices. To communicate between the two CPU, you
can go thru the DPRAM built-in on the hard-core which takes care of
different clock domain. |

[2004-6-24 11:31:49] |
| [问：science] |
nios ii 是否兼容nios 的程序？如兼容是哪种兼容？ |
| [答：Brian] |
NiosII is a new 32-bit architecture and is not binary compatible with
Nios. But you can easily port the old code from Nios to NiosII either
using Legacy SDK mode or do the full migration. The details can be found
in our Application Notes #350. |

increased. |
[2004-6-24 11:34:08] |
| [问：yu.liu] |
NIOS提供浮点运算吗? |
| [答：Brian] |
Neither Nios or NiosII does not have native FPU. It is currently in
the plan to add FPU to Avalon Bus. For now, all floating point operation
are emulated by software library but you can add floating point operation
as custom instruction to boost the performance. |
[2004-6-24 11:36:27] |
| [问：Fentus] |
請問NiosII最高能提供的時脈是多少? |

| [答：Elliott] |
Dear Sir,there are a lot of processors in world.but, most of
the processors are "fixed" chips.if you want to develop new projects
or modify your previous projects,you have to modify or re-design your PCB
even change /add peripheral components.this tell us,traditional
solutions are have no flexibility.so,if you uses nios,you can
enhance your system in "chip"!!you can have most flexibility and
high performance! |

software.The Nios II Development Kit, Stratix Edition includes the
following:Nios II family of embedded processors, soft embedded
core configurable processor Nios II integrated development environment
(IDE) Library of standard microprocessor peripherals Network
protocols software library SOPC Builder system development tool
Quartus? II design software, including the SOPC Builder system
development tool One-year license Windows platform only |

软件开发,主要就是对添加到nios
process中的自定义指令进行调用吗?为什么每个例子都生成了hello_world.c? |
| [答：Kevin] |
Dear Sir,nios software development means application software
,system software even mount OS.hello_world.c is a example of
application software. why does it built-in tools?because it can give
you a simple idea and help user to demostrate your design.in
addition,the customized instruction is used to optimized and enhance
processor.by example: if you need floating point oreration,you can
implement the circuit and add to ALU. |

Altera産品中有無低成本語音處理方案？謝謝！ |
| [答：Sam] |
Cyclone family 再配合IP |

Did NIOSII have MMU inside? |
| [答：Elliott] |
dear sir:NIOSII NO MMU INSIDE. |

| [问：hnzqw2002] |
用sopc builder设计系统,必须要添加nios
process吗,是不是只有添加了nios process ,其他的组件才能工作? |
| [答：Bill] |
Nios
processor不是必须的，但是系统中至少要有一个master的设备才可以，你可以自己设计一个到Avalon的master设备接口就可以了 |

| [问：fwdelta] |
Nios? II 處理器對網路的處理能力如何？ |
| [答：Brian] |
For NiosII, it comes with LWIP TCP/IP stack. Our tests has shown that
with optimization, you can get over 40Mbps transmission throughput on
100Mbps network with Nios. We expect NiosII can get even higher
performance. |

NIOS 的软核成本是多少？ |
| [答：Sam] |
如過使用最精簡的版本,EP1C3這顆FPGA即可使用,價錢部分可詢問當地代理商 |

| [问：gaozg] |
是否有LVDS应用的实例可以参考？ |
| [答：Elliott] |
yes , you can in altera serach it or documentation library
can find it. |

| [问：ty010496] |
NIOSII跟NIOS有什麽區別，新版本的NIOSII，能最高提供多高的主頻?他現在具有MMU嗎？對作業系統的支援怎麽樣？現在有多少作業系統支援他？ |
| [答：Brian] |
For Fmax, it depends on which FPGA devices you choose. But the final
fmax also depends on your whole system, but not just how fast CPU can
run.The current version does not have MMU support, but it would be
added in future version. There are about 7 RTOS/OS supporting Nios now,
including uC/OS-II & uCLinux. |

| [问：wood88] |
Nios II CPU 軟核能否直接應用於産品中，是否需要付費？ |
| [答：Sam] |
Yes, all they need to do is just get a NiosII Development Kit and get
the NiosII license at no additional cost
